- TRC = Total Residual Chlorine Samples were collected in two 2.5 gallon cubitainers. Temperature was measured in each cubitainer upon arrival.
- 4. Sample Manipulation: Samples from Outf all 101 and intake were warmed to test temperature (25.0 +/- 1.0 oC) in a warm water bath.
Aliquots of Outfall 101 and Intake samples were UV-treated through a 40-watt Smart UV Sterilizer (manufactured by Emperor Aquatics, Inc.) for 2 minutes.
